What Does a T1 NAM Do?

The T1 NAM acts as an interface between the T1 digital network and the customer

premises equipment, converting signals received from the DTE to bipolar signals that

can be transmitted over T1 and Fractional T1 lines. The 9261 T1 NAM also provides an

additional T1 network interface connector. Typical applications include:

HWide Area Networks (WANs)

HChannel extension

HVideo teleconferencing

Installing the I/O Card

The NAM’s I/O card provides the COM port, network, and

DTE connections. The I/O card inserts directly behind the NAM

that it supports. Slot numbers are identical (in this case, Slot 01)

to facilitate correct installation.

1. Remove the I/O card from the shipping box. Handle only

by the top and bottom edges to avoid damaging the card.

2. At the rear of the housing, align the I/O card with the

upper and lower tracks of the slot. Push gently towards

the midplane until it stops and you cannot push the card

any further.

Installing the T1 NAM

!WARNING:

Do NOT remove any jumpers located on the battery. To do so can cause

non-volatile memory loss. Should a jumper become separated from the

battery, contact your service representative immediately.

!HANDLING PRECAUTIONS FOR STATIC-SENSITIVE DEVICES

This product is designed to protect sensitive

components from damage due to electrostatic

discharge (ESD) during normal operation. When

performing installation procedures, however,

take proper static control precautions to prevent

damage to equipment. If you are not sure of the

proper static control precautions, contact your

nearest sales or service representative.

The NAM is always installed in Slot 01.

CAUTION:

Be sure that you install the NAM in the correct slot so that it mates with its

matching I/O card. Otherwise, you could damage your card.

1. Remove the housing’s bezel, if applicable. See the housing installation instructions

for information.

2. Remove the NAM from the shipping box. Handle only by the top and bottom edges

to avoid damaging the card.

3. At the front of the housing, align the NAM with the upper and lower tracks of

Slot 01.
